There is a lack of research studies on periurethral cleansing before catheterization among home care patients. The purpose of this study was to compare the risk of acquiring symptomatic urinary tract infections through the conventional practice of using 0.05% chlorhexidine gluconate (CHG) versus sterile water for periurethral cleansing before insertion of an indwelling urinary catheter.
A randomized controlled trial was used, and subjects were randomly allocated to either the sterile water group or the 0.05% CHG group. Urine specimens for culture were collected 4 times for each subject within 2 weeks.
Seventy-four urine samples were collected in 20 subjects (sterile water group, 8; 0.05% CHG group, 12). There was no significant difference in colonization count between the 2 groups. In addition, none of the subjects in the 2 groups developed symptomatic bacteriuria.
Using sterile water to clean the periurethral area before catheterization among home care patients will not increase the risk for urinary tract infections.
对于居家护理患者，在导尿前进行尿道周围清洁的研究较少。本研究的目的是比较在留置导尿管插入前，使用0.05%葡萄糖酸氯己定（CHG）与无菌水进行尿道周围清洁的常规做法导致发生有症状尿路感染的风险。
采用随机对照试验，将受试者随机分配至无菌水组或0.05%CHG组。在2周内为每位受试者收集4次尿液培养标本。
20名受试者共收集了74份尿液样本（无菌水组8份；0.05%CHG组12份）。两组之间的定植菌数量无显著差异。此外，两组中均无受试者发生有症状菌尿。
对于居家护理患者，在导尿前使用无菌水清洁尿道周围区域不会增加尿路感染的风险。
